Paul…thanks for responding. When I transferred my 99 settings, as best as possible, into the 02 operating system I had big time KR - including places I should have had none. When I used the stock...

nevinsb...they are relatively new stock sensors for a 99 vette.

Joecar. Thanks for the reply. It isn’t that straight forward. Parameters B6229, B6230 & B6231 are in the 99 OS but not the 02 OS. B6256, B6257, B6258, B6259 & B6255 are in the 02 OS but not the 99...

I have a 99 vette converted to a 02 Operating System (12212156). Everything is working OK, but I am not comfortable with the Knock System. With the 99 OS, when I heard knock/ping I got KR. When I...

Joecar & 5.7ute…Went to the track today. First run with B0701 enabled. Same problem, fixed 11.70. Second run, B0107 disabled. Cured the problem. Tracked Commanded B3618 AFRs. Thanks guys. Was a...

Joecar…My B3659, piston protection, is set at 12.947. Also, where this is occurring, the rest are set at B1208=12.947, B3603=12.947, B3605=12.947, & B3618=12.46 to 12.72. I am set up with functioning...

5.7ute…no I haven’t tried it with B0701 disabled. Will try this weekend at the strip. Don’t really have a place to run the car out around here.

Joecar, does “COTP” mean converter over...

5.7ute, thanks for reply…I run Random Tech cat converters. B0701 is enabled, but temp settings have been increased significantly. Stock 02 Z06/my settings degreesC = low 830/859, medium 840/867,...

Recently converted a 99 vette “12584929” OS to a 02 “12212156” OS. Transferred most setting over from previous tune. Every thing works except commanded AFR suddenly drops to 11.70 about...

I remember reading sometime ago a post from someone that had knock sensor/KR problems with a 99 to 02 OS conversion, but have had no luck tracking in search.

I have a well sorted out tune in a 1999 Vet with 99 operating system. It's a forged Lingenfelter 383cu short block, AFR205 heads, Lingenfelter GT11 cam, Yank SS3600 converter, etc. Car is a daily...

My experience with 99 to 02 operating system conversion was big time knock sensor/KR problems. Car ran fine, was functional, but couldn’t sort out KR problems - went back to 99 operating system....

Paul/Blacky. Well, you were correct. Updated and ran a scan this morning - all PIDs validated. Thanks again for your attention and assistance.

Thanks for the reply Paul/Blacky. Will download/update tonight and try again in the morning. Thanks again.

I am trying to do some idle RAFIG/RAFPN tuning using the associated following PIDs:
IAC_LTD_DMA
IAC_LTPN_DMA
IAC_STD_DMA
IAC_STPN_DMA
None of these PIDs will validate. They are there, just won’t...

ChipsByAl & driver456/Paul, thanks very much for the suggestions. At first I set them aside thinking it couldn’t be misfire, since I had shut off misfire by setting “Engine DTC Processing...

ChipsByAl. Hope I do this reply correctly, its the first for me. Thanks very much your input. The misfire codes are turned off, before and after the latest reflashes - and no codes are set when the...

Hi. New to the Forum. I have been using a tune in a 99 vette with A4 and Yank SY3500 for sometime with no problems. Recently purchased EFILive and made a few re-flashes to change LTFTs and timing (no...
